Options: book a 30-minute discovery call (free, no commitment) or submit a project brief. DiaDraw does not work with gambling, casino, addiction products, or harm industries. # ============================================================ # FREQUENTLY ASKED QUESTIONS (consolidated across all pages) # ============================================================ Q: Do I need to have everything figured out before reaching out? A: No. DiaDraw regularly works with clients who start with "I have a problem and don't know how to solve it." That's often better than a detailed brief that has already committed to the wrong solution. Q: Is the discovery call actually free? A: Yes. 30 minutes, no slides, no forced close. They ask questions, you talk about your situation, they tell you honestly if they're a good fit. If they're not, they'll say so. Q: Do clients own the code after a project? A: Completely and unconditionally. Code, repository, infrastructure, and documentation all transfer to the client. No dependency by design. Q: Can DiaDraw work with an existing codebase? A: Yes — embedding into existing teams and codebases is one of their most common engagements. Q: How long does onboarding take for team enhancement? A: Typically 5–10 working days from discovery call to signed agreement. Engineers are usually making meaningful contributions within their first sprint. Q: Does DiaDraw work with software they didn't build for long-term support? A: Yes, frequently. Initial codebase review is included in the onboarding fee. Q: What if a team enhancement engineer leaves? A: DiaDraw manages the transition — knowledge transfer, replacement, overlap period. Client doesn't absorb that risk. Q: What industries does DiaDraw refuse to work with? A: Gambling, casino, addiction products, predatory finance, and any industry designed to harm. # ============================================================ # SITEMAP (all known URLs) # ============================================================ https://diadraw.com/ https://diadraw.com/about https://diadraw.com/contact https://diadraw.com/careers https://diadraw.com/case-studies https://diadraw.com/client-reviews https://diadraw.com/blog https://diadraw.com/ai-call-agent https://diadraw.com/ai-document-platform https://diadraw.com/hr-management https://diadraw.com/custom-software https://diadraw.com/vibe-coded-audit https://diadraw.com/team-enhancement https://diadraw.com/small-business-ops https://diadraw.com/long-term-support https://diadraw.com/ai-project-estimator https://diadraw.com/privacy-policy https://diadraw.com/terms
